空间尘粒微损收集新技术的探讨

A NEW METHOD FOR COLLECTING COSMIC DUST WITH MINIMAL DAMAGE

阐述了空间尘粒微损收集的基本概念、意义及相关定义,对微损或柔性收集技术的国内外研究与应用现状进行了归纳。提出了对于空间尘粒进行微损收集的一种新技术设想,介绍了其基本工作原理,针对作为收集器探头核心的缓冲介质材料进行了设计与选用的分析方法研究,在理论分析基础上选择了适用的数值模拟算法—光滑质点流体动力学(SPH)法,为进一步的研究工作提供了基础理论依据与基本分析方法。

This paper explains the basic concepts,related definitions and significance about the technique for collectingcosmic dust with minimal damage,and summarizes the latest research and application statues in this field. Herein,wepropose a new method for cosmic dust collection,presenting its working principle. Meanwhile,we studied the analyticalmethods for the design and selection of the buffer materials which are used to make the core part for the collector probe. Inaddition,SPH（Smoothing Particle Hydrodynamics）was used to simulate the colleting process. The results provide the theoreticalbasis and fundamental analytical method for future research in this area.
